MPI + OpenMP: A Hybrid Scheme of Parallel Programming and Computing

Yuxing Peng, Scientific Computing Consultant, Research Computing Center

Wednesday, March 25, 2015, 1:00 to 3:00 p.m. | Kathleen A. Zar Room, John Crerar Library

Message-Passing (used by MPI) and Shared-Memory (used by OpenMP) are two main concepts of the parallel programming and computing. For a long time MPI has been the dominant approach used on HPC clusters that are based on high-speed networks. In recent years, the clock rates (frequency) of CPUs have reached their limit, and further improvement of CPU performance is mostly gained from multicore techniques, resulting more and more emphasis on OpenMP. Nowadays, computer clusters with multicore processers have introduced a heterogeneous hierarchical parallelism to programmers. Therefore, a hybrid scheme of combining the benefits from both MPI and OpenMP has been widely considered and adopted in developing high-performance parallel software.

This tutorial includes two parts. In the first part, the lecturer will give a brief overview of MPI and OpenMP programming and a basic introduction of hybrid parallel computing, followed by case studies and practices with several experimental problems. In the second part, the tutorial will focus on compiling and building packages with the hybrid parallel scheme on different cluster platforms and on how to configure the computing tasks to gain the best performance. The larger context of the “hybrid” scheme of parallel computing used by GPU, APU, MICS and special-purpose processors will also be discussed.
